ICS Cool Energy’s Top 5 Tips to Help Reduce Costs in Process Cooling Systems

Discover ICS Cool Energy’s top strategies to enhance efficiency and reduce costs in your process cooling systems. In this blog, they delve into the best practices for maintenance, water quality checks, system upgrades, and more to optimise your operations and achieve significant savings.

1. Keep your chilled system maintained frequently

Industrial and process applications depend on process temperature control systems to maintain operations and businesses.

Improperly maintained equipment can fail to provide the required level of efficiency, shortening its lifespan and increasing operating costs.

Planned preventative maintenance carried out effectively by qualified engineers will give you the tools and support to keep the equipment in optimal shape, minimise energy consumption and limit downtime. This frequency should align with how often the equipment is used and how critical it is to operations.

The expense of replacing parts that could have delivered a higher lifetime value, the time it takes to wait for the part, and the subsequent multiple engineer call-outs, plus the cost to your business from downtime, will far outweigh the price of a preventative maintenance plan. Outsourcing your chiller plant maintenance will help free up your internal resources, reduce your costs and keep your chiller performing at optimal conditions for longer.

With a service level tailored to your application and business needs, you can benefit from the assistance of an extensive team of qualified service technicians that provide 24/7, 365 emergency and planned support.

For your peace of mind, depend on technicians proficient in different makes and models of temperature control equipment and those that are also fully conversant with the current F-gas regulations on the safe handling of refrigerants, Control of Substances Hazardous to Health (COSHH) and Health and Safety Risk Assessment Regulations.

2. Carry out water quality checks and treatment

Efficiency, longevity, and safe operation of closed-circuit process chillers are critical and should be top of mind for those responsible.

Water treatment is a fundamental part of a chiller’s operation and maintenance, ensuring efficient and reliable operation. Your chilled system water needs to be treated with the correct dose of high-quality inhibited glycol to protect it from freezing, bacteria build-up, and corrosion.

Taking samples of your system water as part of your planned preventative maintenance program and carrying out pH tests will help you determine the quality. If the water samples fall outside the recommended pH level, a water treatment program can be followed to correct the problem. This could save you the cost of a breakdown and replacement of equipment and pipework.

Should your systems show signs of increased suspended solids, corrosion, or other debris, several devices can be used to remove such contamination.

This includes strainers, filters, magnetic filters, dirt separators, combined air and dirt separators, and commonly found side stream filtration.

A number of systems have side-stream filtration included at the design stage to safeguard some of these issues.

Such equipment is easy to install and has a simple solids removal process.

Side stream filters are designed to constantly pass 5-15% of the circulating water through a filter housing, resulting in the total system volume being filtered 2 to 3 times every 24 hours.

3. Upgrade your chiller to a high-efficiency and high-performance unit

A chiller’s average lifespan depends on how heavily it’s used and how well it is maintained.

Manufacturing process chillers, for example, tend to be used much more heavily than chillers for comfort purposes.

As a guiding principle, if your chiller for process cooling is 8-10 years+, it is worth considering upgrading to the latest high-performance technologies, such as the i-Chiller, designed with process applications in mind from the ground up.

This move can result in savings on your energy costs and maintenance costs and provide greater reassurance with a new 5-year warranty.

The latest ICS temperature control solutions are available in the FLEX Membership, a long-term exchange programme. FLEX Membership subscriptions give customers access to the latest equipment with the flexibility of an operating expense. As part of the flexible package, customers receive the equipment, preventive and 24/7 emergency maintenance, replacements and upgrades for an all-inclusive monthly rate.

This allows them to transform their process temperature control system from a fixed asset into a dynamic solution that will be up-to-date with their changing business and process needs.

FLEX is an all-inclusive service that removes risk and enables you to pay only for what you use.

4.      Relocate your chiller plant externally and use a free cooling coil

As autumn and winter approach and the ambient temperature drops, preparing to capitalise on free cooling could save you up to 70% on your energy costs. When the ambient temperature drops 1°C below your desired operating temperature, you can utilise partial free cooling to cool your process.

Free cooling is a concrete solution that will reduce mechanical energy consumption, lower the carbon footprint, reduce the load on mechanical parts, reduce maintenance costs, and extend the life of your cooling equipment.

5.       Replace cooling towers

Cooling towers are expensive to run, maintain and waste a lot of water. To put this in monetary terms, for every £39k spent running a cooling tower, you would expect to spend £10k running an adiabatic cooler – providing a saving of around 75%. If the saving of money alone isn’t enough, you could seriously boost your environmental credentials too.

Providing significant savings on water usage, they require significantly less maintenance and operational costs and no ongoing chemical treatment or registration with local authorities while operating at optimal efficiency in high ambient temperatures.

For every 70 buckets of water a cooling tower uses, you would expect to use 1 with an adiabatic cooler – saving you 93% on your water costs and conserving a vital resource.

Replacing your cooling towers will save you this cost annually and reduce health and safety risks.
